Cant detect browser's close button is clicked

[topash]

If user clicks the browser's close button then want to do some processing. But not able to detect the Browser's close button event. Can it be done with Javascript?

The closest you can get is to use onUnload (http://developer.netscape.com/docs/manuals/communicator/jsref/evnt24.htm#1012516), which will fire when the user leaves the page (via a link, typing in the address bar or closing the browser).

Unfortunately Netscape does not recognize that event when you close the window using the "X" close button. IE does have the onbeforeunload event that might work for you, but again it is not supported by Netscape.
